Many thanks to SWLing Post contributor, Emilio Ruiz, who writes:

I [note you] have published movies scenes with radios and I remember one of my favorite movies about nature, science, silence, wolves and Inuit culture called “Never Cry Wolf” I’m sharing with you and all readers of SWLing Post blog a radio (I don’t know what brand is, I think is military radio) appear in Never Cry Wolf movie.

I love this scene because the heterodyne sound is a particular sound that drives us crazy to everyone who loves radio!! jaja 😛

The video was extracted from the original Beta format movie, sorry for
the quality.

Thank you for sharing, Emilio!

That heterodyne sound leads me to believe they obtained it using a regenerative receiver. I’ve heard that squeal so many times tuning regen receivers!

I’ll add this post to our ever growing archive of radios in film!
